Cary Instruments
founded 1966
Cary Instruments had its origins in the Applied Physics Corporation founded by Howard Cary, William W. Miller, and George W. Downs in 1946. In 1947, the Applied Physics Corporation delivered its first recording UV-Vis spectrophotometer, the so-called Cary 11, to the Mellon Institute in Pittsburgh, Pennsylvania. Many other research facilities would acquire one. Because of the importance of this product, the company began to use Cary Instruments as a brand name by the mid-1950s.
In 1966, Varian Associates bought the Applied Physics Corporation, renamed it Cary Instruments, and made it a subsidiary. It was located at this time in Monrovia, California. In 1972, Cary Instruments was relocated to Palo Alto.
By 1955, APPLIED PHYSICS CORPORATION was already using Cary Instruments as a brand name and the Cary [chart paper] logo. See Anal. Chem., 1955, 27 (3), pp 48A–48A. DOI: 10.1021/ac60099a754
Through 1958, the address was in Pasadena. In 1959 advertisements, we see the Monrovia address:
